What is Webhook?
Webhooks Explained: Stop Polling, Start Listening! ?
Polling is your app asking a server "any updates yet?" over and over — wasting CPU and bandwidth. A webhook flips it: you give a service like Stripe or GitHub a public URL, and they fire an HTTP POST with JSON to your backend the instant an event happens.
Your server replies 200 OK so they know it landed. If you're down, they retry later. And since the endpoint is public, every payload is signed with a secret key so your app can verify it's authentic and block spoofed requests.
Polling = you asking repeatedly. Webhook = the service reaching out to you.
